The method

The gym principle,
for your whole life.

Lifters don't start with their max. They add a little weight each week. StackAHabit does the same for reading, running, focus, sleep — anything you want to get better at.

01 · START EASY

Week 1 is easy on purpose

A starting point so small you'll hit it on a busy day. Momentum first.

02 · WEEKLY TARGETS

The week is what counts

Aim for five days out of seven. Tuesday can go sideways and you still win the week.

03 · LEVEL UP

You never go backwards

Hit the target, the next level unlocks. Miss it, you hold your level and go again.

How it works

From goal to next level
in four steps.

STEP 01

Tell it what you want to build.

Answer a few quick questions, or start from a ready-made habit stack. Health, focus, mindset, discipline — your call.

Habit quiz: what are we stacking?
STEP 02

Get a plan that grows with you.

Your personalized, AI-designed progression: a small first step, then a little more each week. Edit any step by hand, or ask the AI to adjust it.

STEP 03

Show up. Win the week.

Check in with one tap. Your target is weekly, so every day adds up and the week is what counts. Reminders land when you choose.

STEP 04

Level up. Repeat.

Hit your target and the next level unlocks on Monday. Miss it and you hold your level for another go. Every week, you're a little further up the stack.

What is progressive overload for habits?
It's the principle behind every strength program: start at a level you can handle, then increase it a little each week. StackAHabit applies it to any habit. Read 5 minutes this week, 10 next week, 15 after that — and the habit grows with you.
Is StackAHabit free?
Yes. There's no paywall right now. A Pro plan is coming later — download before then and you're a founding member, so every feature available today stays free on your account.
Do I need to check in every single day?
No. You set a weekly target — say, 5 of 7 days — and aim to hit the week. Hit it and you level up. Miss it and you hold your current level for another week. You never get moved down.
Can I build more than one habit?
Yes. Run as many habit stacks as you like, side by side. Each one has its own level and pace.
Can I make my own habits?
Absolutely. Start from a ready-made habit stack, let the AI design one from your goal, or build a fully custom progression step by step.
Is it on Android?
Android is in beta on Google Play. and we'll send your invite.
Is my data private?
Yes. See our privacy policy for exactly what we store and how it's handled. You can delete your account at any time.
